GOLD-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 618,270, dated January24, 1899.

Application filed April 23, 1898. Serial No- 6'78,589. (N0 model.)

To all whom it may concern:

Be it known that we, FRANKLIN E. JACKSON and LU OIUs R. HENLEY, citizensof the United States, residing at Greentown, in the county of Howard andState of Indiana,have invented new and useful Improvements inGold-Separators, of which the following is a specification.

Our invention relates to apparatus for separating precious metalsfrom'earth containing the same; .and its object is to provide animproved construction of such apparatus by which we secure importantadvantages with respect to efficiency in use.

The invention consists in the novel construction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of agold-separating apparatus constructed in accordance with ourinvention.Fig. 2 is a central longitudinal sectional view.

In the said drawings the reference-numeral 1 designates a water-tankprovided near its upper end with a spout or pipe 2, having a valve 3 foropening and closing communication between said spout and tank. Thisspout communicates with a perforated pipe 4, located above or in aninclined sluice-box 5. Connected with this sluice-box, at the lower endthereof, is a vertical pipe 6, provided with a pipe 7 near the lowerend, which communicates with said tank and is provided with a valve orstop-cock 8. At the lower end of pipe 6 is a receptacle 9, of glass orother transparent material, which receives the gold separated from thedirt, as hereinafter described. The said pipe 6 intermediate its ends isprovided with a curved pipe 10, which communicates with an inclinedtrough 11, provided with a screen 12 at the inner end, below which is aninclined box 13. Communicating with the lower end of this box is avertical pipe ll, provided with a curved discharge-pipe 15 and with apipe 16, extending to and communr eating with the tank and provided witha valve 17. At the lower end of pipe 13 is a transparent receptacle 18,similar to the receptacle 0.

Theoperation is as follows The auriferousbearing dirt and gravel areplaced in the sluice-box and water admitted to the perforated pipe fromthe tank, which, escaping into the sluice-box, dissolves the dirt,forming a plastic mass. This will escape at the lower end of thesluice-box into the vertical pipe 6, when it will meet the water-supplyadmitted to the pipe 6 from the tank through a pipe 7. This water-supplyis so regulated that it will carry the dirt, gravel, and other likedebris out through the curved pipe 10, while the gold will fall into thereceptacle 9. From said pipe 10 the dirt and gravel and any gold whichmay be carried over therewith escape into the trough 11 and from thencethrough the screen to box 13 and pipe 14, where it will meet watersupplied from the tank through pipe 17, when the above operation will berepeated, the tailings escaping through pipe 15 and the gold settling inthe receptacle 18.

Having thus fully described our invention, what we claim is In aconcentrating-machine, the combina tion with the elevated water-tank,the inclined sluice-box, and the perforated pipe located above saidsluice-box and extending from end to end thereof and connected with saidtank, of the vertical pipe connected with the lower end of saidsluice-box having a sight-receptacle at the lower end, and providedintermediate its ends with a pipe leading to said tank, the curved pipeconnected with said vertical pipe above the connection of the pipeleading to the tank, the inclined trough having a box connected with itsupper end provided with a screen flush with the bottom of the trough andsaid trough provided with a vertical pipe connected with said tank andhaving a curved discharge-pipe above said connection and with asight-receptacle at the lower end, substantially as described.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
